Document Summary
Cell biology: the study of cells and their structure, function and behavior (requires creative instruments and techniques) Reductionist: studying the parts can explain the whole. Smallest units exhibiting the characteristics of life. Able to reproduce themselves by their own efforts. Building block from which all organisms are constructed. Cell tissue organ multicellular organism. Small (5 to 20 micrometers), invisible to the naked eye. Highly complex (because of pathways and structures) and organized (organelles) Composed of a genetic program, dna(deoxyribonucleic acid) (genes encode information to build each cell, for cellular respiration, activity and structure) Capable of producing more of themselves (each daughter cell receives a complete set of genetic instructions) Acquire and use energy (can convert glucose to atp, photosynthesis provides fuel for all living organisms and animal cells derive energy from the products of photosynthesis) Can carry out metabolism (the entirety of all chemical reactions within a body) Respond to stimuli (respond to growth factors)
